WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 297,230, dated April 22, 1884. l

Application tiled. October 15, 1883. (No model.)

To all whom it may concern:

Be it known that I, H. K. COTTON, of Mount Vernon, in the county of Knox and State of Ohio, have invented certainnew and useful Improvements in VVindow-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this speciiication.

My invention relates to an improvement in window-screens; and it consists in the combination of a screen, which is made in two parts, so as to be extensible, with the metallic slides which are applied to the inner edge of each part, and a sharp-pointed projection, which extends from the upper edge ofthe stationary part, the movable part having its upper edge beveled away, as will be more fully described hereinafter.

The object of my invention is to construct an extensible screen in such a A manner that after the stationary part of the screen has been placed in position and the window-sash lowered upon it the removable portion can be moved freely back and forth without interfering with the stationary part in any manner.

Figure l is a side elevation of a screen embodying my invention, partly extended. Fig. 2 is a vertical cross-section ofthe same.

A represents the stationary part ofthe frame,

which will be made of any desired shape or screen under the sash at one side,and then lower thesash upon the top of the screen, when this sharp point O will serve to hold the screen in place by catching in the lower edge of the sash. The operator then has but to catch hold of the movable portion D of the screen and push it out to the full width of` the window. By this construction the operator has but to hold up the sash with one hand and then place the screenin position with theother, when both hands are left free to be used in eX- tending the screen, as may be desired.

The movable portion of the screen D is attached to the stationary portion by means of suitable slides, F, which are attached to the inner edges of the two parts of the screen, and have one'of their ends turned at right angles, so as to catch in a groove, G, made in the other part of the screen. These slides serve to hold the two parts of the screen together, and yet allow either part to be freely moved back and forth upon the other. These slides are applied to the inner edges of the screen, as here shown, so as to be entirely out of the way of the window-sash when it descends upon the stationary part, and to be out of the way when the movable part of the screen is being moved back and forth. Vere these slides applied to the outer edges of the screens, they would only catch against the top ofthe window-frame and the lower edge of the sash, and thus interfere with the free movement of the movable part D. In order to prevent the upper edge ofthe movable portion D of the screen from catching against the lower edge of the sash, and thus interfering with the free movement of the movable part, this edge is beveled away, as shown at I, so that the sash will come in contact with the stationary part A only. The two parts, where they come in contact with each other at their top and lower edges, are cut away, so as bring the parts more closely together, and then the flange O on the one part bears against the netting of the movable portion, so as to prevent any insects from passing in between them, and thus getting into the house.

By the construction above described it is only necessary to place the stationary part A in position, lower` the sash upon it, and then the removable part of the screen can be extended so as to till the whole of the opening. This movable part, sliding freely back and forth upon the stationary part, which is held in position by means of the sharp point and the sash, can be opened at any time to allow the blinds to be opened or closed, or allow pots or iiowers outside of the window to be watered, or for any other similar purpose.
